This document describes how to work with Scylla’s large partitions table.
Large partitions table can be used to trace large partitions in a cluster.
The table is updated every time a partition is written and/or deleted,and includes a compaction process which flushes memtables to SSTables.

Configured the large partitions detection threshold can be set in the scylla.yaml file with the compaction_large_partition_warning_threshold_mb parameter (default: 100MB). Each partition bigger than this threshold is going to be reported in the large_partitions table and generate a warning in the log.
